'T0 all whom it may con/cern,.-

Be it known thatLlvIARTIN ERICKsEN, a citizen of the United States,residing at La Crosse, in the county of La Crosse and State ofWisconsin, have invented certain' new and useful Improvements inCompressors; and I do declare the following to be a full, clear, and

exact descriptionof the invention, such as will enable others skilled inthe art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to the figures of reference markedthereon, which form a part of this specification.

My invention relates to compressors for making bundles of corn-stalks,sugar-cane,

laths, and like articles; and it consists in the improved' constructionof parts, as will be hereinafter more fully set forth.

Referring to the-.accompanying drawings, in

Ywhich the same reference-numerals indicate corresponding parts in eachof the figures, Figure 1 is a perspective view of the device oomplete.Fig. 2 is a sectional view. Fig. 3 is a longitudinal sectional view, andFig. 4 is a view of the device adapted for compressing the bundle inmore than one place.

. Referring more particularly to thedrawings, 1 indicates the'frame ofthe machine,

which is preferably made out of gas-pipe, to make. it light andportable. It is usually made about three feet long and provided withonly three feet, so that it Will rest solidlyl Wherever'placed. Theupper portion is provided with diverging arms 2 2, Within which thearticles to be compressed are placed.

About midway of the cross-piece 3 is rigidly secured a frame 4, theupper portion of which is. formedor provided with a Ablock 5, the upperface of which is preferably curved to correspond with the diverging armsat the ends, and is substantially on a line with them, so that anythingwhich is placed Within the arms will also be supported at the middle.Journaled upon the shaft within the frame arel two sheaves' 6, the inneror adjacent rims of which are formed into cogs or teeth. The sheaves areplaced'far enough apart for the introduction between them of a pinion 7,which can be rotated by means of a crank or handle 8, applied to theouter end of the shaft 9. The pinion is provided with a ratchet 10,

with which a pawl 11 engages and prevents the backward rotation of thepinion. If it is desired to reverse the movement of the sheaves forreleasing the bundle quickly, the frame 4 may be extended outwardly fromthe cross-piece and the peripheries of the sheaves far enough to permitof a latch 12 being placed between the inner side of the frame and theouter surface of the ratchet. This latch is preferably hinged to the'frame at the crank. The pinion is preferably providedv- Y with aboutthree teeth, as this will enable the sheaves to be placed as closetogether as possible and yet cause at least one tooth to be inengagement with each of the sheaves and cause its rotation. slightlytapering, it can be more readily inserted between the sheaves 'after ithas been Withdrawn, which is done by raising the latch and slipping thespindle through its bearing in the frame.

The periphery of each sheave is provided with a groove 13, within whichis placed a rope or cord 1,4, the free end of which is passed up througha hole 15 inthe block 5.

The opposite end of the rope is secured to the sheave by means of aneyebolt 16, which may be tightened upon the rope by means of a nut 17upon the inner en'd, the nut being placed within an opening 18 in thesheave, whereby it can be easily operated. Vhen the rope stretches somuch as to interfere with the eflciency ofthe device, the eyebolt isloosened and the ropedrawn through it as far as desiredl and the boltthen tightened. The free ends of the ropes are provided with the buckles19, which are hooked together when the device is to be operated and areseparated when the bundle is to be removed. The holes 15 through theblock 5, through which the ropes pass, are inclined substantiallytangential to the peripheries of the sheaves, so that By making thepinion IOO , the ropes will pass through them without too much wear, andI prefer to slightly notch the top of the block, as shown at 20, so thatthe ropes can be sunk even with the surface of the block and notinterfere with the articles that are placed thereon to be tied.

After a bundle has been compressed as tightly as desired, it isnecessary to tie it with a cord, which should be placed as close to thecompressor-cord as possible. To do this a hole 2l is preferably madetransversely the block, in which short pieces of twine can be placed,the ends of which twine will hang down out of the way,but which can bebrought up around the bundle when the bundle is to be tied. The hole ispreferably made with a narrow saw-kerf, leading into it from the top ofthe block, which will prevent any of the pieces of twine from coming outof the hole, except the one that is being used, the kerf beingsufficiently narrow to prevent this.

In operation the latch is raised and the pinion is drawn back out ofengagement with the sheaves. The ropes 14C are then drawn out as far aspossible, each sheave being provided with a pin or stop 22, whichengages with the frame 4 and prevents the further ro tation of thesheave in that direction. Pieces of twine are placed within thereceptacle or hole 21, and the articles to be compressed are placedwithin the arms 2 of the frame. The buckles of the ropes are then unitedand the pinion 7 inserted between the sheaves and rotated,which willdraw the ropes tightly around 3 the bundle. The ends of a piece of twineare then brought together around the bundle and tied, after which thepressure upon the bundle may be removed by raising the latch and` Thebuckles are then uuhooked and the ropes 14 are drawn out, as before,until the stops on the sheaves withdrawing the pinion.

strike the frame. In this manner the articles can vbe made into verycompact bundles andV tied with but little trouble. rl`he size of thebundle can be varied to suit the wishes, or from about two feet to a fewinches in diame` ter, the circumference of the sheaves limiting thelarger size.

As above described, the machineis adapted for tying corns-talks,sugar-cane, and such like articles; but for lath and some other thingsthe bundle must be tied in two places or at each end. To do this thecross-bar 3 is made long enough to receive two sets of sheaves at thedistance apart that it is de sired to locate the binding-cord. A sleevej23 is inserted between the two sets of sheaves,`

and, if desired, firmly connected to the adjacent sheaves of each set,so that turning one set by a crank will also turn the other set inunison therewith, although the sleeve may be dispensed with or not beconnected with the through 'might be varied without departing from thespirit of my invention, the main requisite being that the sheaves beturned in opposite directions, so as to draw the ropes tightly aroundthe bundles.

Having thus described my invention, I claiml. In a compressor, thecombination, with a `frame having a cross-piece, two oppositelymovingsheaves journaled thereon, a pinion engaging with said sheaves, a framefor sup porting said pinion, and a cord upon each sheave, said cordsbeing adapted to be connected together and drawn tightly around a bundleplaced upon the frame, substantially as described.

2. In a comprcssor,tl1e combination, with a frame having a cross-piece,of two sheaves journaled thereon` a frame secured to said crosspiece, apinion engaging with said sheaves, the shaft or spindle of which ismovable longitudinally through its bearing in said frame, a latch forholding the pinion in engagement with the sheaves, and a rope upon eachsheave, said ropes heilig adapted to be connected together and drawntightly around a bundle placed upon the frame, substantially asdescribed.

3. In a compressor, the combination, with a frame having a cross-piece,of sheayes journaled thereon, a frame secured to the crosspiece,provided with a block having a binden twine receptacle, a cord aroundeach sheave, the free end of which' passes up through said block, andmeans for rotating thesheaves, substantially as described.

4. In a compressor, the combination, with a frame having a cross-piece,of sheaves journaled thereon and rotating in opposite direc- IOO tions,an eyebolt in each sheave, a rope sccured to each sheave by means of theeyebolt, and means for securing the ropes together and rotating thesheaves, substantially as described.
